Although marginalities may not affect the functionality of a circuit immediately after manufacturing, they can degrade into hard failures and must be screened out during manufacturing test to prevent early life failures. Furthermore, their evolution in the field must be proactively monitored by periodic tests before actual failures occur. In recent years small delay faults have gained increasing attention as possible indicators of marginal hardware. However, small delay faults on short paths may be undetectable even with advanced timing aware ATPG. Faster-than-at-speed test (FAST) can detect such hidden delay faults, but so far FAST has mainly been restricted to manufacturing test. AU - Kampmann, Matthias AU - A.

The HLT is based on task formats, which promote algebraic thinking in terms of generalizing rules from the analysis of patterns and should be familiar to students from their mathematics education experiences in elementary school. Second, we analyze two students' actual learning process based on Peircean semiotics. The analysis shows that the actual learning process diverges from the hypothesized learning process in that the students do not relate the different levels of the diagrams in a way that allows them to extrapolate the rule for the subtraction of negative numbers. Based on this finding, we point out consequences for the design of the tasks.

Accordingly, new types of applications take an advantage of the processing and flexibility provided by the wireless network. A common property between these applications is that the processing is not running on only one single node, but it is broken-down into smaller tasks that can run over multiple nodes, i.e., exploiting the in-network processing. We study a special variant of in-network processing, where the application is given by a graph; the processing tasks have predefined connections to be executed in a predefined sequence. The problem of embedding an application graph into a network is commonly known as Virtual Network Embedding (VNE). In this paper, we present a Genetic Algorithm (GA) solution to solve this wireless VNE problem, where we take into account the interference and multi-cast properties. We show that the GA has a good performance and fast execution compared to the optimization problem.

By separating firms into groups based on exclusions of recurring expenses before material restatements occur this paper investigates whether market participants are misled based on ex-ante non-GAAP reporting. The results show a decline in cumulative abnormal returns (–11.8% aggressive non-GAAP Reporting vs. –2.7% non-aggressive non-GAAP reporting), reduction in overvaluation (–22.18% vs. no decline) and losses in the earnings response coefficient (–51.8% vs. no significant decline) for firms with prior aggressive non-GAAP reporting. Further, we document that investors are less responsive to aggressively reported non-GAAP earnings ex-post, indicating that increased attention enhances investor’s ability to see through the quality of non-GAAP exclusions.
